I've tried with
Replay Media Catcher . After klicked the "start recording" button a file with .swf appeared and start downloading it but it stops at 250kb then after few minutes the program crashed. I repeatedly do it the same way but everytime gave me the same result.
Here is the link of the weekly live church streaming I mentioned

The other one is the non live ones

I hope someone can help me with this.
